We apply an advanced autocorrelation method to simulated UHECRs which includes their directional as well as energy information. Without explicit knowledge of the UHECR sources, such measurements are sensitive to the number of sources and to the magnetic field strength subjected to the UHECRs. Using a UHECR Monte Carlo model including sources, random walk propagation and a coherent deflection, we explain the procedure of reconstructing the allowed phase space of the model parameters from a simulated autocorrelation measurement.", "revisions": [ { "version": "v2", "updated": "2010-02-02T16:10:49.000Z" } ], "analyses": { "subjects": [ "98.35.Eg", "98.70.Sa", "98.62.En" ], "keywords": [ "ultra high energy cosmic ray", "high energy cosmic ray data", "measuring cosmic magnetic fields" ], "tags": [ "journal article" ], "publication": { "journal": "Astroparticle Physics", "year": 2010, "month": "May", "volume": 33, "number": 4, "pages": 201 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 819150, "adsabs": "2010APh....33..201E" } } }
